Post Grant Proceedings

Post Grant Proceedings

Aside from litigation before the federal district courts, the validity of granted U.S. patents may be challenged before the U.S. Patent and Trademark Office. Post grant proceedings are in fact a changing and vibrant area of patent law, as the America Invents Act (AIA)  has changed the landscape for such post grant challenges. Following AIA, the collection of post grant proceedings used to effect patent validity challenges comprises Ex Parte Reexamination, Inter Partes Reexamination (phased out on September 15, 2012), Post-Grant Review, Inter Partes Review and Supplemental Examination.

Traditionally avoided by litigation defendants, on the theory that post grant submissions of prior art could strengthen patent validity once withstanding such a challenge, today post grant proceedings have become an effective tool for defendants. Conversely, patent enforcers without expertise in post grant proceedings may find their litigations stayed, and their ability to pursue infringers significantly curtailed or entirely lost. Concurrently dealing with the differing notions of validity and status of patent claims before the U.S. Patent and Trademark Office, during post grant proceedings, and before a federal district court in a pending litigation, present a challenge to even the most highly skilled of patent litigators.

Trademarks may be challenged before the U.S. Patent and Trademark Office as well. Under the Lanham Act, parties who may be damaged by the actual or proposed registration of a trademark may be entitled to challenge the registration. If the mark has been published for proposed registration on the Principal Register, the party can oppose the registration, in a writing filed following the proposed mark’s publication in the Official Gazette. IPLL’s trademark counsel and litigators are adept at opposition proceedings, having successfully challenged and defended many opposition proceedings over their expansive careers.
